APPARATUS FOR TREATING LIQUIDS WITH GASES.

forming part of Letters Patent No. 344,322, dated June 22, 1886.

Application filed September 28. 1885.

To all whom it may concern.-

Be it known that I, GEORGE LUNGE, a citizen of the United Kingdom ofGreat Britain and Ireland, residing in Zurich, Switzerland, haveinvented certain new and useful Improvements in Apparatus for the Actionof Gases upon Liquids or Solids, of which the following is aspecification.

The object of this my present invention is an apparatus for bringinggases in intimate contact with liquid or solid bodies, whereby, inconformity to the well-known requirement of many operations ofindustrial chemistry, the action of the gases upon the liquids or solidstakes place as perfectly as possible.

In the accompanying drawings, Figure 1 is a vertical section of myapparatus. Fig. 2 is a bottom view of an essential part of theapparatus; Fig. 3, a vertical transverse section, taken in the plane ofthe line, a [1 Fig. 2, and Fig. at a vertical transverse section takenin the plane of the line 8 r, Fig. 2, of the same part.

The vessel A, forming the base of the apparatus, is provided with theinlet pipe a for the gases, and the outlet-pipe It for theliquid, and issurrounded by a trough, 0, into which plate 13, in order to constitute aso-called hydraulic or water lute. The plate Bis likewise surrounded bya trough c, in which is placed the downward-projecting socket c of afollowing plate, B Upon this plate B there is placed another plate, 13*,of similar construction, and thus any number of plates, 13* B, ofsimilar construction, may be successively superposed over one another,always forming hydraulic lutes between the trough e of each one plateand the socket c of each following plate. In these plates 13 B 13 rowsof holes d are disposed in such a way that these rows of holes aresituated alternately on the right and on the left side of the plates.The upper ends of the holes d are surrounded by low collars, but theremainder of the upper surfaces of the plates are plain and horizontal.The lower surfaces of the plates are preferably as shown by Fig. l ofthe drawings, inclined in such manner that they descend from the holes(I to the opposite side of the plate. Furrows Z, Figs. 2, 4, departingfrom the holes (I, the purpose of which is Serial No. 178. 159. (Nomodel.)

hereinafter specified, may be advantageously disposed upon the inclinedlower surfaces.

lVe will suppose that in the apparatus an action of gases upon a liquidis to take place. The gases in this case enter the vessel 15 through thepipe (I, while the liquid to be treated is flowing through the pipefupouthe top or covering plate C of the tower-like apparatus. Thiscovering-plate C is analogous in construction to the other plates, BBBonly, in case the gases which leave the apparatus are still to beconveyed to some other apparatus the holes d of the covering-plate O areprovided with hydraulic lutes joining these holes to the pipes whichconvey the gases to the following apparatus. The gases ascending throughthe holes (Z pass the apparatus in a zigzag line, and are therebybrought into most intimate contact with the liquid, which, flowing overthe low collars which surround the holes d, descends from plate toplate, and finally flows off in a very concentrated state through thepipe 7:. The gases do not only come into contact with the thin layer ofliquid spread upon the upper surfaces of the plates B B B, but also withthose layers of liquid which adhere to the inclined lower surfaces ofthose plates, the liquid flowing down by adhesion from the holes (1 overthe inclined lower surfaces of the plates. By this means there is a veryextensive surface of contact afforded between the gases and the liquid.

In order to form the hydraulic lutes, water or any other convenientliquid, as the case may be, is made to run through the cock y into theuppermost trough, c, of the apparatus. The liquid descends by means ofoverflows situated alternately at opposite sides of the troughs 0,passes in this way through all the hydraulic lutes, and finally leavesthe trough 1), running off at h. This stream of liquid through thehydraulic lutes, which may either be continuous or intermittent, servesin many cases advantageously for cooling the apparatus. 7

In some cases the apparatus hereabove described may be slightlymodified, in the manner represented by Figs. 5 to 9 of the drawings.Fig. 5 is a vertical section of the modified apparatus; Fig. 6, the topView, and Fig. 7 the bottom View, of the covering-plate C. Fig. 8 is thetop View of one of the other plates. Fig. 9 is a partbf the verticalsection, Fig. 5, on a larger scale.

The plates B B B are in this modified construction of the apparatusprovided with very many small holes, the total cross-section of which isgreater than that of the gas-inlet pipe at. The lower surface of theplates is plain and horizontal. The upper surface may be slightlyhollowed out at m, Fig. 9, between the small holes. from one plate tothe following one, so that the liquid traversing the holes falls upon asolid piece of the following plate, and is thereby scattered about.thoroughly dispersed and caused to continuously change their course bythe manner of arranging the perforations of the plates, and

The same arrangement is also given to the covering-plate 0, Fig. 6,which may have in each compartment one or more larger holes, (1, insteadof a greater number of small ones. These larger holes d, as alreadystated in the description of the first apparatus, and represented byFig. 5, can be easily connected by means of water-lutes with the pipeswhich convey the gases to some other piece of apparatus.

The liquid may advantageously be spread over the surface of thecovering-plate O by means of a reaction-wheel 70, Fig. 5.

In order to distribute the liquid uniformly over the following-plate,furrows n, Fig. 7, may depart radially from the holes 01 on the lowersurface of the covering-plate G.

If in such apparatus gases have to act upon These latter are alternatedThe ascending gases are solid bodies, or mixtures of solid and liquidbodies, the plates B B B may be singly filled with the solid, or themixture of solid and liquid substances,and superposed over one another,and as soon as the operation is ended they may be lifted off and emptiedone after the other.

The apparatus shown by'Figs. 1 to 4 is more appropriate for treatingsolid substances in the shape of a powder or a mud,while the apparatusshown by Figs. 5 to 9 is more convenient for treating coarselygranulated substances.

The apparatus may be constructed of stoneware, earthenware, metal, wood,or any other convenient material. Instead of the square or circularshape of the plates B B B, (shown 1 by the drawings,) any other form maybe em ployed.

I claim as my invention 1. The combination, in a condenser, of vessel A,having pipes a R,with superposed perforated plates B B, 8m, connected byhydraulic lutes, substantially-as and for the pur- GEORGE LUNGE.
